Geomembrane: Carbofol®
Carbofol® HDPE geomembranes
Manufactured using high quality polyethylene resins. Carbofol® is manufactured in various thicknesses and up to 7.50m width. For sealing applications on slopes, Carbofol® is produced with an embossed structure.
Typical solutions with Carbofol®
- Landfill caps and base seals
- Canals, ponds and reservoirs
- Tunnels and buildings
- Mining
- Storage, filling, handling, manufacturing, treatment and use of contaminated liquids
Project advantages
- Excellent chemical resistance due to selected raw materials
- High interface friction angles with embossed structured surface
- Installation advantages with up to 7.50m wide liner
- High Melt Flow Index (MFI) allows an excellent welding performance
- Available according to GM-13 and with BAM and DIBt approval
Selected advantages of Carbofol®
Advantage 1: Carbofol® long-term durability
Durability and high chemical resistance are ensured by carefully selected resins and a special stabilising system, which is aligned with the resin type. An enormous amount of field and lab data supports this performance.
Advantage 2: Special embossed surface structure allows a safe construction on steep slopes
New optimised BF/TF (bottom friction/top friction) embossed surface structure has been developed to increase shear strength towards typical shearing partners.
Advantage 3: Carbofol® HDPE liner comes with weld protection stripes and lateral marking
The Carbofol® geomembranes are provided with a white edge mark on both sides. These edge marks indicate the recommended areas of overlapping and are a visual aid during the installation. Furthermore, a thin protective sheet (~150mm wide) is attached to both edges and is peeled off immediately prior to the welding process to provide an absolutely clean welding area.
Advantage 4: HDPE Geomembrane with high Melt Flow Rate (MFR)
Carbofol® HDPE geomembranes feature a Melt Flow Rate (MFR) between 1 and 3g/10 minutes tested at 190°C/5kg and thus have the advantage of a large welding window. This makes Carbofol® geomembranes flexible and easy to handle during on-site installation. The speed at which welding processes can be carried out on Carbofol® geomembranes is distinctly higher than that of other liners with an MFR less than 1g/10min. This gives Carbofol® yet another major benefit during on-site installation and welding.
